Key result
Loss of 19q13 in dedifferentiated liposarcoma was associated with shorter median disease-specific survival (27 vs >90 months; P<0.0025) and increased risk of local recurrence (HR 2.86; P=0.013).
Why the study?
Do specific copy number alterations predict dedifferentiation, morphology, and prognosis in liposarcoma?

May support refined prognosis in dedifferentiated liposarcoma; hypothesis-generating for copy number-based stratification pending validation.
Observational (n=107)
Do specific copy number alterations predict dedifferentiation, morphology, and prognosis in liposarcoma?
Hazard Ratio: 2.86
p-value: p=0.013
Copy number losses, particularly 19q13, improve risk stratification and predict poor prognosis in dedifferentiated liposarcoma.
Crago et al. (2012) conducted an observational in Well-differentiated and dedifferentiated liposarcoma (n=107). Loss of 19q13 vs. Diploid 19q13 was evaluated on Local recurrence (HR 2.86, p=0.013). Loss of 19q13 in dedifferentiated liposarcoma was associated with shorter median disease-specific survival (27 vs >90 months; P<0.0025) and increased risk of local recurrence (HR 2.86; P=0.013).
